GEO Technology is radically new thinking
The GEO R&D Project has, to date, resulted in the following patent applications:
The GEO Hyperboloid Reflective Wavesource™ differs radically from the megaphone-variant type horns you know and love (or hate). “Tried and true” methods will produce entirely unexpected results. HRW technology produces precise and predictable results.
The Configurable Directivity Flange. A waveguide that allows the operator to alter its behaviour. An unprecedented NEXO development that is easy to use – once you know how and when.
The Phase Directivity Device needs no operator input to function, but it is reassuring to know that the coupling of the midrange of the system is considered as important as the high frequencies…
DSP-driven Directional Sub-bass devices are a new approach to controlling LF/VLF acoustic energy.
GEO is not hard to use when you understand how…
The technology behind GEO is revolutionary, but it is grounded in years of practical experience with the problems of delivering high quality professional sound to large audiences at high SPL levels. The GEO toolbox includes NS-1 - a simple yet powerful and highly predictive design tool. The array assembly system is keyed to the design software and will easily enable you to deploy your design with great precision. NEXO Digital TDcontroller technology provide driver protection and system optimization for the GEO S and LS series.
GEO is a high precision system
The GEO HRW™ controls acoustic energy more precisely than other multiple element waveguides. It also makes GEO less forgiving of mistakes. Whilst conventional horns never combine into a coherent array, they may deliver acceptable results even if the design and deployment of the system is less than optimal. This is not the case with GEO where careless installation produces catastrophic results.
A GEO Tangent Array is not a “line array”
GEO Technology is equally effective in designing and deploying tangent curved vertical or horizontal arrays. For best results in a specific application the user needs to know how multi-speaker arrays interact with audience geometry, along with the benefits and drawbacks of curved vertical arrays and horizontal arrays.
Curved tangent arrays require different design techniques
In the past, sound reinforcement professionals have worked with horizontal arrays that use conventional horns to deliver [more or less] ‘equal power to equal angles’. Curved vertical arrays are now designed to deliver [more or less] equal power to equal areas’. When arrays use conventional horns, the lack of precision, overlap and interference masks errors in array design and aiming. The highly precise GEO wavesource responds accurately, consistently and predictably to the design and deployment of a curved vertical tangent array. This is why the GEO rigging system is designed to control angular splay to 0.1° precision.
GEO curved tangent arrays require different operational techniques
Over the years, system designers and operators have developed a number of signal processing techniques to disguise and partly overcome the limitations of horn design. “Frequency shading,” “amplitude shading,” “High Frequency compensation”, all of these are tools of the advanced sound system operator. NONE OF THESE TECHNIQUES ARE APPLICABLE TO GEO TANGENT ARRAYS. Instead of enhancing the array’s performance they will severely degrade it.
Take time to learn how to get great results with GEO Technology. It is an investment that will pay off in more satisfied clients, more efficient operating procedures and more recognition for your skill as a sound system designer and operator. A comprehensive understanding of GEO theory, tangent arrays, and specific features of the GEO S Series will help you to operate your system at its full potential.

PLEASE READ CAREFULLY BEFORE PROCEEDING
BASIC PRECAUTIONS
Do not open the speaker system or attempt to disassemble the internal parts or modify them in any way. The speaker system contains no user-serviceable parts. If it should appear to be malfunctioning or damaged, discontinue use immediately and have it inspected by qualified NEXO service personnel.
Water exposure: Do not expose the speaker system to direct rain, do not use it near water or in wet conditions. Do not place containers with liquid on speaker system as they might spill into openings. If any liquid such as water seeps into the speaker system, have it inspected by qualified NEXO personnel.
Sun exposure: Do not expose the speaker system to direct sun.
Operating temperature with temperate climate: 0°C to +40°C (-20°C to +60°C for storage).
SYSTEM DEPLOYMENT SAFETY RULES
Read User Manual before deployment. Before use of enclosed speaker system, please ensure that anyone involved in system deployment understands the rigging – stacking – pole mounting safety rules as described in the speaker system User Manual. Failure to do this exposes people to potential injury or death.
Please check the web site nexo-sa.com for the latest update.
Always consult qualified NEXO personnel if the device installation requires construction work and make sure to observe the following precautions:
Mounting precautions
- choose mounting hardware and an installation location that can support 4 times the weight of the speaker system;
- do not use speaker system handles for suspended installation;
- do not expose speaker system to excessive dust or vibration, or extreme cold or heat to prevent possibility of component damage;
- do not place the speaker system in an unstable position from which it might fall accidentally;
- if speaker systems use a stand, ensure that stand specifications are adapted, and that stand height does not exceed 1.40m/55”; never move the stand while the speaker is in position.
- in case of wind greater than 8 on Beaufort scale (72km/h – 45mph), a touring system has to be landed or an additional securing has to be implemented.
- for fixed installations, wind loading has to be taken into account in accordance to the national standards.
Connection and powering precautions
- remove all connected cables before moving the speaker system;
- turn off AC power of all power amplifier units before connecting the speaker system;
- when turning on the AC power to the audio system, always turn on the power amplifier last; when turning the AC power off, always turn off the power amplifier first;
- when used in cold conditions, a gradual power ramp up should be applied to the system on a 5 mn period to allow the loudspeaker components to stabilize during the very first minutes of usage.
Inspect the speaker system periodically.

HIGH SOUND PRESSURE LEVELS
Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient period of time. The U.S. Government’s Occupational and Health Administration (OSHA) has specified the following permissible noise level exposures: Sound Duration Per
Day In Hours Sound Level dBA, Slow Response
8 90
6 92
4 95
3 97
2 100
1 ½ 102
1 105
½ 110
¼ or less 115
According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors to the ear canals or over the ears must be worn when operating this amplification system in order to prevent permanent hearing loss, if exposure is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation.

3.2 Cabling
NEXO recommends the exclusive use of multi-conductor cables to connect the system: the cable kit is compatible with all the cabinets, and there is no possible confusion between LF, MF and HF sections.
Cable choice consists mainly of selecting cables of the correct sectional dimension (size) in relation to the load resistance and the cable length. Too small a cable section will increase both its serial resistance and its capacitance; this reduces the electrical power delivered to the loudspeaker and can also induce response (damping factor) variations.
For a serial resistance less or equal to 4% of the load impedance (damping factor = 25), the recommended cable length is given by:
Lmax = Z x S S in mm2, Z in Ohm, Lmax in meters
The table below indicates these values, for 3 common sizes.
Load Impedance () 2 2.6 4 5.3 8 16
Cable section Recommended Cable Length
1,5 mm² (AWG #15) 3m/10ft 3m/13ft 6m/20ft 8m/26ft 12m/39ft 24m/79ft
2,5 mm² (AWG #13) 5m/16ft 7m/23ft 10m/33ft 13m/44ft 20m/66ft 40m/131ft
4 mm² (AWG #11) 8m/26ft 10m/33ft 16m/52ft 21m/70ft 32m/105ft 64m/210ft
6 mm2 (AWG #9) 12m/40ft 16m/52ft 24m/79ft 32m/104ft 48m/160ft 96m/315ft
Maximum allowed length is 4 times recommended length.
Example:
GEO S12 EN54 module has a 16 nominal impedance in passive mode. When connecting 4 modules in parallel, total load
impedance becomes 4.
Recommended length for 4mm2 / (AWG#11) is 16m / 52ft, maximum allowed length is 64m / 208ft.
IMPORTANT
Long speaker cables induce capacitive effects – up to hundreds of pF depending on the quality of the cable - with a low-pass effect on high frequencies. If long speaker cables must be used, ensure that they
do not remain coiled while in use.

NS-1 SIMULATION SOFTWARE
System Manual GEOS12 EN54 Page 15 / 53
5 NS-1 SIMULATION SOFTWARE
NS-1 software is a R&D simulation tool derived application. It processes measured speaker data with complex mathematical algorithms to assist the user in optimizing system design. Due to the complexity of the interaction of multiple cabinets, it is simply not possible to reliably design curved vertical arrays without using the processing power of a computer to predict the optimum array structure for a given audience geometry. The design logic is far more complex than looking at a section drawing of the venue, measuring the overall angle needed to cover the audience from the cluster location, and dividing by 10 degrees to determine the required amount number of GEO S1210 EN54 cabinets.
NS-1 is an easy to use tool that allows to shape the energy leaving the cluster to fit the audience. It predicts pressure levels radiated from the system to ensure enough cabinets are provided for the application, as well as mechanical constraints for safe flown systems.
In addition, it provides mechanical information for all clusters in agreement with Structural Analysis Reports (available in the Help section): dimensions, weight, gravity centre position, forces, moments, working load and safety factor.
GEO S12 EN54 Structural Analysis Report is currently being certified by German Certification Organization RWTUV systems GmbH.
NS-1 installation package includes all NEXO User Manuals, Structural Analysis Reports and Certificates PDF files.
NS-1 is a freeware available on nexo-sa.com
IMPORTANT
Never install a GEO S12 EN54 cluster without checking its acoustical performances and mechanical safety in NS-1 prior to installation.
Any question or bug report please contact technical@nexo.fr
NS-1 GEO S12 ACOUSTIC PAGE
CONFIGURABLE DIRECTIVITY DEVICE
Page 16 / 53 System Manual GEOS12 EN54
6 CONFIGURABLE DIRECTIVITY DEVICE
The GEO Wavesource controls dispersion of acoustic energy using a hyperboloid acoustical reflector in the “coupling plane” (the vertical plane of a curved vertical tangent array) and a diffraction slot in the “non-coupling plane” (the horizontal plane of a curved vertical tangent array). The patented Configurable Directivity Device consists of flanges that alter the diffraction s lot’s exit flare rate.
6.1 Installing & removing GEO’s Configurable Directivity Devices
GEO S12 EN54 are shipped in the 80° dispersion configuration, 120° CDDTM flanges are an optional accessory (GPT-FLG).
To change horizontal dispersion from 80° to 120° and vice-versa:
- Remove the front grille
- Remove the 6 screws from the waveguide
- Position the CDDTM flanges on the waveguide and fix it with the provided screws and washers
- Reinstall the grille
CONFIGURABLE DIRECTIVITY DEVICE
System Manual GEOS12 EN54 Page 17 / 53
6.2 When & where to use Configurable Directivity flanges
The diagrams show audience area coverage for a stereo system. While the GEO cluster will deliver even SPL from the front to the rear of this audience area, there are “holes” near the front in the centre and at the outside edges. We cannot fill the outside coverage gaps without enlarging the centre gap, and vice versa (left figure below).
If 120° Configurable Directivity Devices are installed at the bottom cabinet of the clusters, coverage will look more like the pattern in right figure below.
-6dB coverage, all GEO S12 in 80° configuration -6dB coverage, bottom GEO S12 in 120° configuration
In curved vertical arrays, the 120° Configurable Directivity Device can be used:
• On the bottom row of curved vertical arrays, to fill in coverage gaps in the front rows.
• On all rows of curved vertical arrays, in cases where 120° of horizontal coverage is preferred to 80°.
IMPORTANT
Installing or removing one of the two flanges anticipating asymmetrical coverage will degrade both coverage and frequency response.
GEO S12 EN54 HARDWARE SETUP PROCEDURE
Page 18 / 53 System Manual GEOS12 EN54
7 GEO S12 EN54 HARDWARE SETUP PROCEDURE
Before proceeding with assembly of GEO S12 EN54 arrays, please ensure that the components are present and undamaged. A component list is appended to this manual. In the event of any shortage, please contact your supplier.
For maximum efficiency the GEO S12 EN54 rigging system requires three experienced persons for set-up: typically, one motor hoist operator, and one operator per side of the array. Good synchronisation and crosscheck between the operators are key elements for a reliable and safe set-up.
7.1 Safety first
GEO S12 EN54 Rigging System structural computations and related documents are available in NS-1 or at NEXO (info@nexo.fr) upon request.
We include this section to remind you of safe practice when flying the GEO S12 EN54 system. Please read it carefully. However, user must always apply his or her knowledge, experience and common sense. If in any doubt, seek advice from your supplier or NEXO agent.
This manual offers guidance only for GEO S12 EN54 loudspeaker systems. References in this manual to other rigging equipment such as motor hoists, steels, shackles etc. are made to clarify the description of rigging procedures. The user must ensure that operators are properly trained by other agencies in the use of these items.
The GEO S12 EN54 Rigging System has been optimised for the deployment of curved vertical or horizontal tangent arrays of GEO S12 EN54 loudspeakers. Angle adjustment between cabinets has been limited to specific settings to ensure correct acoustic coupling.
The GEO S12 EN54 Rigging System is a professional precision tool set and should be handled with extreme care. Only persons who are fully conversant with the operation of the GEO S12 EN54 Rigging System and provided with suitable safety equipment should deploy GEO Arrays. Misuse of the GEO S12 EN54 Rigging System could lead to dangerous consequences.
Used and maintained correctly, the GEO S12 EN54 Rigging System will give many years of reliable service in portable systems. Please take the time to read and understand this manual. Always use NS-1 to determine the optimum angle settings for a particular venue, hang point and curved vertical GEO S12 EN54. Applied forces and moments are strongly cabinet quantity and angle configuration dependent. Cluster configuration must be implemented and validated in NS-1 prior to installation.
7.1.1 Flown systems safety
Always inspect all the rigging components and cabinets for damage before assembly. Pay special attention to the lifting points, and safety clips. If you suspect that any of the components are damaged or defective, DO NOT USE THE AFFECTED PARTS. Contact your supplier for replacements.
Read this manual carefully. Also, be familiar with the manuals and safe working procedures for any ancillary equipment that will be used with the GEO S12 EN54 Rigging System.
Applied forces and moments are strongly cabinet quantity and angle configuration dependent. Cluster configuration must be implemented and validated in NS-1 prior to installation.
Ensure that all local and National regulations regarding the safety and operation of flying equipment are understood and adhered to. Information on these regulations can usually be obtained from Local Government Offices.
When deploying a GEO S12 EN54 system always wear protective headwear, footwear and eye protection.
Do not allow inexperienced persons to handle a GEO S12 EN54 system. Installation personnel should be trained in loudspeaker flying techniques and should be fully conversant with this manual.
Ensure that motor hoists, hoist control systems and ancillary rigging components are currently certified as safe and that they pass a visual inspection prior to use.
Ensure that public and personnel are not allowed to pass beneath the system during the installation process. The work area should be isolated from public access.
Never leave the system unattended during the installation process.
Do not place any object, no matter how small or light, on top of the system during the installation procedure. The object may fall when the system is flown and is likely to cause injury.
Secondary safety steels must be installed once the system has been flown to the operating height. Secondary steels must be fitted irrespective of requirements of the local safety standards applicable to the territory.
Ensure that the system is secure and prevented from pivoting around the motor hoist.
Avoid any form of excessive dynamic loading to the assembly (structural computations on GEO S12 EN54 Rigging System are based on a 1/1.2 factor for hoist or motor acceleration).
NEVER attach any item to the GEO S12 EN54 system other than the GEO S12 EN54 accessories.
When flying outdoor systems ensure that the system is not exposed to excessive wind or snow loads and is protected from rainfall.

In case of wind greater than 8 on Beaufort scale (72km/h – 45mph), a touring system has to be landed or an additional securing has to be implanted.
For fixed installations, wind loading has to be taken into account in accordance to the national standards.
The GEO S12 EN54 Rigging System requires regular inspection and testing by a competent test centre. NEXO recommend that the system is load tested and certified annually or more frequently if local regulations require.
When de-rigging the system ensure that the same duty of care is given to the procedure as for the installation. Pack GEO S12 EN54 components carefully to prevent damage in transit.
7.1.2 Ground stacking safety
Statistically, many more injuries occur due to unstable ground stacked PA systems than those associated with flown systems. There are several reasons for this fact, however the message is clear:
Always survey the supporting structure upon which a ground stack is to be built. Always look beneath PA wings to inspect the deck support and if necessary ask for the stage scrims and dressings be removed to allow access.
If the stage surface slopes, as it does in some theatres, ensure that the system is prevented from sliding forwards due to vibration. This may require the fitting of timber battens to the stage floor.
For outdoor systems ensure that that the system is protected from wind forces which might cause the ground stack to become unstable. Wind forces can be huge, especially upon large systems, and should never be underestimated. Observe meteorological forecasts, calculate the “worst case” effect upon the system prior to erection and ensure that the system is secured appropriately.
Take care when stacking cabinets. Always employ safe lifting procedures and never attempt to build stacks without sufficient personnel and equipment.
Never allow anyone, whether operators, artists or members of the public to climb onto a ground stacked PA system. Anyone who needs to climb over 2m (6 ft) high should be fitted with suitable safely equipment including a clip-on harness. Please refer to local Health and Safety legislation in your territory. Your dealer can help with advice on access to this information.
Apply the same attention to all safety matters when de-stacking systems.
Be aware that safety procedures are as important in the truck and in the warehouse as they are at the venue.
7.1.3 Contacts
Correct training is fundamental to safe practise when working with loudspeakers flying systems. NEXO recommend that users contact local industry associations for information on specialist course.

7.4 Testing and Maintenance of the system
General: GEO is a precision piece of equipment and requires regular attention to maintenance in order to give long and reliable service. NEXO recommends regular testing of loudspeaker rigging components, preferably using a suitable test rig coupled with a visual inspection.
Fasteners: there are several critical points in the GEO S12 EN54 cabinets.
Of primary concern are:
a) The grid screws attaching the grid to the cabinet
b) The machine screws attaching the connecting plates to the cabinet.
c) The screws attaching the directivity flanges to the front of the cabinet.
These fasteners should be regularly checked and tightened as necessary.
Cleaning: The exterior of the cabinet and the rigging system can be cleaned with a damp cloth soaked in mild soapy water. On no account use solvent based cleaners, which may damage the finish of the cabinet
After cleaning, the rigging system must be treated with a suitable lubricant to prevent rusting. NEXO recommends the use of Scottoil FS365 which is a water-based lubricant with a mixture of machine oil, surfactant and anti-rust treatment.

SYSTEM CHECK GUIDELINES
Page 32 / 53 System Manual GEOS12 EN54
8 SYSTEM CHECK GUIDELINES
8.1 Recommended installation tools and equipment
Tape measure – should be 30m/100ft in length and be of durable fibre material. Have one per array available to speed up the installation process.
Laser Inclinometer – For measuring vertical and horizontal angles in the venue.
Spirit level – used to ascertain the trueness of the surface from which the angle measurements originate.
Rangefinder measuring device – either a Disto type laser measure or an optical laser rangefinder can be used. Devices such as the Bushnell ‘Yardage Pro’ sports rangefinders provide sufficiently accuracy and are easy to use. They have the additional advantage of working very well in bright sunlight.
Electronic calculator with trigonometric functions to calculate the height from ground level to points in the room. The formula to calculate height of a point from measured angle and distance is:
Height of point = Sin (vertical angle in degrees) x distance to point
NB: Take care when using spreadsheets as they calculate using radians by default. To convert degrees to radians, use the formula:
Angle (in radians) =3.142 x Angle (in degrees)/180
Computer – Laptop or Desktop PC running Windows 8 with the current version of NEXO NS-1 installed. It is not possible to configure a GEO tangent array properly without using NS-1. Note that, when NS-1 designs are prepared prior to arrival at the venue, it is often necessary to modify or update the design to accommodate special circumstances. A PC is absolutely essential to make such changes.
Audio Analysis Software – recommended but not absolutely essential, programs such as SystuneTM, SmaartTM enable rapid and detailed analysis of the installation. Consider taking a training course in using one of these tools if you are not already competent with them – it will pay dividends in increased performance of the system.
8.2 GEO S12 EN54 System Check List
It is essential to execute all these check steps prior to perform a sound check on the “front end” to the system. Following this checklist step by step will prevent many troubles and will save time in the end.
Are the speakers properly connected and angled?
Attach the first series of modules to the bumper.
Before flying, verify that all channels of all modules are functioning properly.
To check that all elements have the proper amplitude and phase, you should listen to the upper boxes at a close distance (<1 meter). You should be able to move from the top to the bottom of the cluster without hearing any change in the tonal balance.
Verify that the angle settings are the same on both sides of each module.
Raise the bumper, attach the next series of modules and repeat the above checks.
Make sure that these series of modules sum properly with the modules above them.
When all the modules are flown, check that the aiming angles are the same left and right.
Make sure that multiple GEO S12 EN54 are summing properly: 6 dB gain per doubling of quantity.
Final Pre-Sound Check Check
Play a CD track mono left, and then right: both sides must sound strictly identical. When listening in the centre between Left and Right GEO S12s EN54, everything from LF to HF should be located to the “phantom centre” position. If not, repeat the above check sequence to identify the source of the problem.
